NESCO is getting power supply from three 220KV interface points i.e., Duburi, Joda and PGCIL sub-station (S/S) at Kuchei. There are twelve nos. of GRID S/S under NESCO at Balasore, Jaleswar, Baripada, Rairangpur, Soro, Bhadrak, Jajpur Town, Jajpur Road, Duburi, Chandikhole, Polaspanga and Joda. To improve the system further there is a proposal for new GRID S/S at Karanjia, Basta, Bhadrak, Anandapur, Barbil and Keonjhar. The construction of Karanjia and Bhadrak Grid are under progress.

NESCO has taken many steps for improving its supply network like commissioning of new 33/11KV S/S, replacing bare conductors by A-B cable, up gradation of power transformers, up rating of 33KV conductors, installation of circuit breakers etc. Pre-monsoon check up is done to minimise line breakdown during rainy season. A separate maintenance group has been formed for timely and regular maintenance of power transformers, distribution transformers, breakers etc. Other technical information regarding distribution network of NESCO are given in the table below.
